Persist `autoscroll` option.

[ekonoval]

Hi, you have a really useful plugin but it's very inconvenient each time to turn-off autoscroll.
I often try to debug page redirects using HTTP-Header-Live but if autoscroll is turned on after each page reload I have to scroll to the top to see the actual redirect and statuses and having tons of useless images, css file logs right under the really valuable info about actual page redirects. And each time I have to not forget to uncheck autoscroll option.
(Actually not after page reload but when I close-reopen Http-Header-Live window)
Would be great to have an ability to set this option state by default.

Also would be great to have an option to clean up the output after each master page reload, though I guess that might be hard to determine and implement.
Thanks for your plugin anyway.
